# FloatingPortal

Portals the floating element into a given container element — by
default, outside of the app root and into the body.

```js
import {FloatingPortal} from '@floating-ui/react';
```

This is necessary to ensure the floating element can appear
outside any potential parent containers that cause clipping (such
as `overflow: hidden`), while retaining its location in the React
tree.

<ShowFor packages={['react-dom']}>

<PackageLimited>@floating-ui/react only</PackageLimited>

</ShowFor>

</PageCard>

```js
function Tooltip() {
  return (
    isOpen && (
      <FloatingPortal>
        <div>Floating element</div>
      </FloatingPortal>
    )
  );
}
```

Context is provided so that portals nested in one another are
appended to their respective parent.

<Notice>
  The portal component should be conditionally rendered based on
  the `isOpen` or mounted state (as seen above), rather than
  always rendered. This allows React Suspense to work as
  expected.
</Notice>

## Props

```ts
interface FloatingPortalProps {
  root?:
    | HTMLElement
    | null
    | React.MutableRefObject<HTMLElement | null>;
  id?: string;
  preserveTabOrder?: boolean;
}
```

### `root{:.keyword}`

Optionally specifies the root node the portal container will be
appended to.

```js
// Element
<FloatingPortal root={rootNode} />
// MutableRefObject
<FloatingPortal root={rootNodeRef} />
```

### `id{:.keyword}`

Optionally selects the node with the id if it exists, or create
it and append it to the specified root (by default
`document.body{:js}`).

```js
<FloatingPortal id="custom-root-id" />
```

### `preserveTabOrder{:.keyword}`

default: `true{:js}`

When using non-modal focus management using
`<FloatingFocusManager />{:js}`, this will preserve the tab order
context based on the React tree instead of the DOM tree.

```js
<FloatingPortal preserveTabOrder={false} />
```

## `useFloatingPortalNode(){:js}`

Exposes the portal container node for custom use in other
components.

```js
function App() {
  const portalNode = useFloatingPortalNode({
    // Accepts `id` and `root` props
  });

  if (portalNode) {
    return createPortal(<div />, portalNode);
  }

  return null;
}
```
